EXTENSION-TABLE.

To all whom it may concern:

Be it known that I, KARoLY KRAL, a subject of the King of Hungary, andresident of the city of New York, in the county of New York and State ofNew York, have invented certain new and useful Improvements inExtension-Tables, of which the following is a specification.

The present invention relates to extension tables, and has for itsobject to provide a table wherein the extension leaves are at all timesattached to the table, whereby such leaves cannot be lost or mislaid.

Another object of the invention is to provide an extension table whichshall be capable of easy adjustment and which is constructed of as fewparts as possible, whereby the device is rendered simpler, cheaper andotherwise better adapted and more convenient for use.

With these and other objects in view, as will more fully hereinafterappear, the invention consists in certain novel features of constructionand arrangements of parts hereinafter more fully described, illustratedin the accompanying drawings, and more particularly pointed out in theappended claims, it being understood that various changes in the form,proportions, size and minor details of construction may be made withoutdeparting from the spirit or sacrificing any advantages of theinvention.

The invention is illustrated in the accompanying drawings, in whichFigure 1 represents a plan view of an extension table constructed inaccordance with the invention as it appears with the extension leavesfolded, Fig. 2 is a section taken on line 2, 2 of Fig. 1, and Fig. 3 isa section taken on line 3, 3 of Fig. 1. Fig. 1 is a front elevation ofthe table with the extension leaves drawn out, and Fig. 5 is a plan Viewof the table extended to its full length.

The main frame of the table, to which the legs or other supports areattached, comprises the side rails 6, 6 and the end rails 7 and 7forming a substantially rectangular base. The side rails 6, 6 areconnected by cross boards 8, 8, to one of which is attached a leg orsupport 9, while four legs or supports 10, 10 are secured to the endrails 7 and 7 moving with the same when the table is extended, wherebythe use of the usually hinged auxiliary legs is done away with.

Rigidly connected with the cross boards Specification of Letters Patent.

Application filed September 20, 1909.

Patented May 10, 1910. Serial No. 518,673.

8, 8 are guide rails 11, 11 and 12, 12, each of which is provided withan upper tongue 13, 13, engaging grooves 14, 1a in the slides 15, 15 and16, 16. The slides 15, 15 are attached to the end rail 7, while theslides 16, 16 are fastened to the end rail 7 the upward movement of theslides relative to the guide rails being prevented by cross boards 17,17, secured to the side rails 6, 6.

The top of the table is of circular configuration and comprises themiddle sections 18, 19 and 20, one arranged on top of the other, and theend sections 21 and each of which is of a thickness which corresponds tothe combined thickness of the middle sections 18, 19 and 20. The section20 is attached to the end section 22, while the sections 18 and 19 arekept in close contact with the sections 21 and 22 by dowel-pins 23, 23,engaging holes in the adjacent parts. The section 18 is attached to twoof the cross boards 8, 8 of the side pieces 6 by means of bolts 24,24,attached. to the section 18 and passing through the cross boards 8. Thebolts are surrounded by coiled springs 25, 25, bearing against thesection 18 and washers 26, 26, resting upon guides 27, 27, through whichthe bolts 24:, 24 pass; the lower ends of the latter carrying heads 28,28, for limiting the upward movement of said bolts. To the sections 21and 22 are pivoted at 29, 29, keepers 30, 30, each of which is providedwith hooks 31 and 32, adapted to engage pins 33, 33, attached to the endrails 7 and 7. More particularly, the hooks 32, 32 engage pins 33, 33when the table is in its closed position, whereby the entire top is keptupon the main frame against the action of the coiled springs 25, 25,while hooks 31, 31 are adapted to coact with the said pins, when thetable is extended.

The operation of the device is as follows: First, the end rail 7 istaken hold of and a pull exerted thereon to move it outwardly with theslides 16, 16. Since the keepers of the section 22 engage theircorresponding pins upon the side rail 7, the section 22 will follow themovement of the side rail 7. If one additional extension leaf issuflicient, the dowel-pins of the sections 18 and 19 are disengaged fromthe corresponding holes of the section 21, whereby the sections 18 and19 will be raised by the springs 25, 25 in such a manner that thesection 19 comes to lie in the plane of the section 21. The sections 20and 22 which have dropped into their lower positions, as the section 7is moved to extend the table one leaf width, are then raised into theplane of the sections 21 and 19, and then all the dowel-pins engagedwith their corresponding holes. The dowel-pins of the section 19engaging the holes in the section 20, and the hooks 32 in engagementwith the pins 33 serve as the supporting means of the sections 20 and22. If, however, it is desired to draw out the table to its full length,both of the rails 7 and 7 are pulled outward. The extension leaves 20and 22 move, in the manner hereinbefore described, with the end rail 7,while the end section 21 moves with the end rail 7 The springs 25, 25are thus left free to act and will thereby raise the sections 18 and 19.Sections 20, 22, and 21 are then lowered into the plane of the section18 and the hooks 31, 31 brought into engagement then with the pins 83,33 of the end rail 7, and 7 respectively. The section 19 is then placedbetween the sections 18 and 21 and when all the dowel-pins are engagedwith their respective holes, a continuous surface is obtained of thepeculiar configuration shown in Fig. 5 of the drawings.

To close the table, obviously the same operations are necessary in areverse order.

What I claim is: r 1. In an extension table, the combination with siderails, of end rails forming with said side rails the main frame of thetable,

supporting legs for said main frame, and a top of clrcular configurationcomprismg three middle sections, one arranged upon the top of the other,and two end sections, each of which is of a thickness corresponding tothe combined thickness of said middle sections.

2. A top for extension tables, comprising a plurality of middlesections, one arranged upon the top of the other, and two end sections,each of which is of a thickness corresponding to the combined thicknessof said middle sections.

3. In an extension table, the combination with side rails, of end railsforming with said side rails the main frame of the table, supportinglegs for said main frame, guide rails attached to said side rails,slides attached to said end rails and engaging said guide rails, and atop of circular configuration comprising three middle sections, onearranged upon the top of the other, and two end sections, each of whichis of a thickness corresponding to the combined thickness of said middlesections.

Signed at New York, in the county of New York and State of New York,this 15th day of September, A. D. 1909.
